That's pretty impressive! What do you put in them when you set them up?I use 8 frame Medium Supers with a 4 inch tray attached to the bottom. The entrance hole is placed in the tray, not the super. Adding the tray gets the internal volume at approx. 40 liters. I have had tremendous success with this size trap. Last year I caught 15 swarms using 10 traps in a little over a month. This is a good way to use older, damaged supers
There are several online calculators you can use to calculate volume of your swarm box. I used this one:
Below is an example. I used to have a few with slide block system to close them in after capture, have switched to use the metal entrance disks.

I use lots of foundationless frames in my apiaries. I run all 8 frame mediums. I sort through all my extra comb coming out of winter. If I have lots of drone comb, I cut it out to melt and use these frames in my traps with an old/dark worker comb in the center of the box. When a swarm moves in, they build pretty much all worker comb, because they are looking primarily at expanding. So, I use swarm trapping as a way to convert drone comb into worker comb. I also use lemongrass oil - will staple a section of straw filled with cotton ball to the back of the hive and add a dropper full of lemongrass oil to it. If I don't use the straw method, I just take a Q-Tip and dip it into the lemongrass oil and place into a sandwich baggie folded and drop it on the floor of the trap. I also make a paste wax using beeswax, lemongrass oil, and olive oil. You can follow these instructions from Linda Tillman:That's pretty impressive! What do you put in them when you set them up?
You could do this I guess, but I dedicate my swarm boxes to trapping. I use French cleats on most of them, so I can take my caught swarm down just by lifting it off my bracket, and placing a new trap in its place.When the box gets populated, simply lift it off your stand, bring it to the yard, and add it to a standard bottom board and you are off to the races.
